Abstract: A brake disk includes a first abrasive disk, a second abrasive disk and a heat dissipation disk co-axially sandwiched between the first abrasive disk and the second abrasive disk. A middle disk is co-axially mounted onto the first abrasive disk and the second abrasive disk, wherein the middle disk is adapted to be mounted to a hub. A specific heat capacity coefficient of the heat dissipation disk is greater than that of the first abrasive disk and the second abrasive disk for absorbing thermal energy from the first abrasive disk and the second abrasive disk and lowering the temperature of the first abrasive disk and the second abrasive disk during braking.

Abstract: A disc brake includes a first casing and a second casing abutting each other to define a receiving space for partially and separately receiving a brake disc. The first casing and the second casing respectively has an axial pushing apparatus mounted therein. Each axial pushing apparatus has a first end outwardly extending through the first/second casing and a second end having a lining pad mounted thereon. The first end of each of the axial pushing apparatus is respectively connected to a lever that is connected to a brake cable. The two axial pushing apparatus inwardly moves the two brake linings to synchronously clamp the two opposite sides of the brake disc for speeding down or stop the bicycle when the brake cable pulls the lever.

Abstract: A pipe connector has a main body, a sleeve and elastic claws. The reducing flanged pipe of the main body is linked to several guiding lugs with a guiding surface. Several inclined pushing discs are formed on the inner wall of the sleeve and abutted with the guiding lugs. A radiative swinging baseline facing the inner wall of the sleeve is formed at the center of the main body. With the lowering force applied to the sleeve, the guiding lug can be elastically accumulated to swing inwards or outwards on the swinging baseline under the guidance of the inclined pushing disc. When the force applied by the user is released, the sleeve will be resumed to move up with the resetting of the guiding lug. The pipe connector of the present invention is characterized by simple construction and more stable guidance with improved applicability and industrial benefits.

Abstract: The present invention provides a handheld tool having a handle, extended into a 3D profile. There is a palm through-hole, being arranged at both sides of the handle and penetrating the handle. The long-shaped palm through-hole is consistent with the long handle, and the pore shape and aperture of the palm through-hole must be suitable for the penetration of a palm. Two first web ribs are formed at two opposite sides of the shorter section of the palm through-hole. The two first web ribs are intended for abutting with the first web of hand. A convex working end is arranged at an extended end of the handle. With this handheld tool, the user can fetch and operate other tools easily while holding this handheld tool, thereby realizing convenient operation with improved applicability.

Abstract: The present invention provides an improved structure of a shadow shield for a vehicle, which is targeted to common vehicles for easy assembly or disassembly. With the help of a rotary rack assembled at the coupling seat of the main frame, the combined vehicle shadow shield can be retracted or unfolded. The swinging end of the rotary rack is provided with a pendulum expansion link, enabling it to drive the shading cloth to fold downwards, and also making the shading cloth fully cover the lateral windows. With the collapsible main frame, the shadow shield can present excellent convenience and efficiency of assembly/disassembly with improved applicability.

Abstract: The present invention provides an improved water flow switching mechanism of a gear-type sprinkler, which addresses problems of typical gear-type sprinklers, such as invalid water switching and poor stability. The gear-type sprinkler includes a water inlet portion, a water outlet portion and accommodating space. A convex framework is additionally placed onto the accommodating space opposite the separate water outlets. Two lateral grooves are defined in the convex framework, each corresponding to a water outlet. So the pivotal portion of the rotary switching seat is assembled centrally into the convex framework. The rotary switching seat is provided with two opposite extension flanges. The extension flange may block the lateral groove of the convex framework in line with the swinging direction of the rotary switching seat. The water-stop area of rotary switching seat is greatly increased, thus ensuring the stability of the water flow switching state and improving performance of the sprinkler.

Abstract: The present invention is a sealing structure for a rotary valve of a squirt gun. The rotary valve is placed into a housing of the squirt gun body between an inlet duct and an outlet duct. The rotary valve is provided with a through hole, and both ends of the rotary valve are connected to a button outside of the squirt gun body. The rotation angle of the rotary valve can be adjusted to control the switching or misalignment state between the through hole of the rotary valve and the inlet duct and the outlet duct. A flexible sealer is placed on the outer wall of the rotary valve opposite to the inlet duct or outlet duct of the squirt gun body. When the through hole of the rotary valve is misaligned with the inlet duct and outlet duct, the flexible sealer is placed opposite to the inlet duct or outlet duct to achieve water-tightness, thereby reducing the components and saving the manufacturing cost for improved industrial applications.

Abstract: The water flow control structure of a water gun includes a movable control tube, stepwise positioning unit, oblique guide and resilient component. When the control tube is moved by the control component, it is turned by the oblique guide and stepwise positioning unit. Each time the first guide of the control tube coordinates with the position of the stepwise positioning unit, it makes the space between the stopper head of the control tube and the water control outlet of the water holder close or open in different degrees to control water flow. The entire control structure is hidden inside the water gun. The repeated movements of the control component can switch the water flow mode, which is convenient and practical.

Abstract: The present invention provides an improved structure of a sprinkler. The invention has a water storage space inside the sprinkler base, so that the water flows into the sprinkler base through water pipe connector. The water fills up the water storage space first and then flows into the sprinkler unit. The sprinkler base is weighed down with water without having other blocks to secure it. The invention not only saves cost but also secures the base as well, which makes it more practical.

Abstract: A revolving lawn sprinkler comprises a rotary guide plate by which the water flow is so controlled as to actuate a lobed wheel, which in turn actuates a rotary disk via a transmission mechanism. A nozzle is mounted on the rotary disk and is provided with a movable joint. The rotary guide plate is forced to change its revolving direction at such time when a projection of the rotary disk comes in contact with a locating block of a top cover of a housing of the lawn sprinkler.

Abstract: A sprinkler structure comprises a support unit, a spray unit, and at least one fastening unit. A water pipe of the spray unit is uprightly supported by the support unit along with the fastening unit comprising a tubular seat, a press block, and a control lever. The tubular seat is provided with a center through hole to accommodate the water pipe, and a through slot in which the press block is pivoted. The control lever is provided at a pivoting end with an eccentric press surface and is fastened pivotally with two pivoting lugs of the tubular seat such that the eccentric press surface pushes the press block to arrest the water pipe at the time when the control lever is swiveled in one direction. The press block releases the water pipe at the time when the control lever is swiveled in other direction.
