Abstract: A gun attachment mounting structure is disclosed to include a base member, which has a coupling groove for coupling to a top coupling bar of the gun body of a gun and locating holes extending from two opposite sides of said coupling portion, retaining members mounted in the base member, each retaining member having two springy clamping arms respectively inserted through the locating holes for clamping the top coupling bar to secure the base member to the gun body, and swivel locking control members respectively mounted in the base member and rotatable to lock the base member to the top coupling bar of the gun body after coupling of the coupling groove to the top coupling bar.

Abstract: An internal red dot sight includes an objective lens formed of a convex lens, a planar eye lens set in a tilt angle relative to the objective lens and facing the concave surface of the objective lens, and a light emitting device set in between the planar eye lens and the objective lens and controlled to emit a point light source onto the eye lens for enabling the eye lens to reflect the point light source and to further produce a virtual point light source on the focal point of the objective lens for viewing by the user.

Abstract: A toy gun is provided with a plurality of protrusions formed on a rear end's circumference of its top gun-body. The protrusions are inserted and fastened to a rear end's inner edge of a bottom gun-body of the toy gun to heighten the combination stability of the top and the bottom gun-body, so that the shooting accuracy of the toy gun can be significantly improved and an accidental falling of the toy gun to break or damage the protrusion at the rear end's bottom edge of the top gun-body can be prevented.

Abstract: A mouse assembly includes a base having an open top for a frame received in the open top of the base. The frame has a protrusion in which a trace sphere is rotatably engaged A reflection board is received in the protrusion and located below the trace sphere. A circuit board with a limit switch is connected to an underside of the frame and located below the reflection board The limited is activated by hitting the under board of the base when pushing the trace sphere. A flexible water-proof plate is mounted to a top of the flame and has an aperture with which the trace sphere is engaged.

Abstract: A payphone coin release device includes a base plate fixed inside the payphone casing and having a pivotal pin extending therefrom to rotatably support thereon a driven link having two opposite arms of which one is rotatably pivoted at one end of an intermediate link and the other one rotatably supports thereon a coin release roller to cooperate with a conventional coin receiving device. The base plate also has a hole through which a shaft rotatably extends to drivingly engage a driving link. The driving link has a pin formed thereon to drivingly engage an intermediate link. The intermediate link is pivoted at two opposite ends to both the driven link and the driving link. The shaft of the driving link extends outside the payphone casing and is connected to a user-actuateable lever so that by actuating the lever, the driving link is rotated to drive, through the connection of the intermediate link, the driven link to rotate about the pivot.

Abstract: A telephone connection cover has multiple holes defined in a top face of the cover; two caps each oppositely formed on a side of the cover; two notches each oppositely defined in a side of the cover, and each adjacent to one of the caps; multiple legs each extending from a corner of the cover for securing each corner of the terminal connection; and a fixing post extending from one side of the cover and into an aperture of the terminal connection. With such an arrangement, the terminal connection cover is able to prevent the terminal connection from being damaged by a falling object and becoming rusty due to the moisture in the air.

Abstract: A coin retrieval device for a pay phone includes a panel having a shaft with a retrieval lever extending radially therefrom. A guide device is pivotably connected to the panel about two pins on two ends of the guide device. The guide device includes a guide plate and a jam plate pivotably connected to the end plate of the guide plate. A gap is defined between the guide plate and the jam plate for coins passing therethrough via a coin slot defined through the guide plate. One of the two pins has a torsion spring mounted thereto which has two ends respectively connected to the retrieval lever and the guide plate. The guide device can be pivoted relative to the panel by lifting the retrieval lever, and a distal end of the jam plate is pivoted toward the coin slot to prevent coins from being inserted into the coin slot.

Abstract: A mother board connector of public telephone is disclosed. The mother board connector includes a first socket base and a second socket base. The first socket base includes a plurality of first socket holes and a plurality of second socket holes on the two opposite ends of the first socket base, respectively, each first socket hole aligned with a respective second socket hole which has a smaller inner radius. A first conducting tube with an outer radius greater than the inner radius of the first socket hole is sleeved into the second socket hole and protrudes out of one end of the second socket hole. The front end of the second socket base includes a plurality of concave holes with respect to the first socket holes. The bottom of the concave hole has a conducting rod connected with a conducting wire to extend the conducting wire out of the second socket base. The concave hole is sleeved with a second conducting tube with an inner radius smaller than the outer radius of the conducting rod.

Abstract: An improved structure of a coin collector cover comprises an upper cover, a cover plate, a buckling piece, a positioning plate and a twisted spring. The upper cover is installed with a coin inlet and a slot. The cover plate is located on the plane of the upper cover. A plurality of teeth are installed on the edge thereof, and a twisted spring is arranged between the cover plate and the upper cover. By the elastic force of the twisted spring, the cover plate may be retained to cover the coin inlet. The buckling piece is pivotally installed on the plane of the upper cover. The edge thereof is installed with a plurality of teeth pieces for being engaged with the teeth of the cover plate. A nose portion is disposed at the edge thereof, while the buckling piece is further installed with a block which is combined with a lock. The edge of the positioning plate is formed with a concave portion for receiving the buckling piece so that the positioning plate can be installed on the plane of the upper cover.

Abstract: A reinforcement pay phone upper housing for mounting to and protecting a pay phone is disclosed, including an outer casing having at least a front panel and two opposite side panels extending from the front panel to be mounted to the upper portion of the pay phone so as to at least cover a portion of a front side and two lateral sides of the upper portion of the pay phone in order to protect the upper portion of the pay phone. An inner plate is arranged inside the outer casing and fixed to an inner surface of the front panel. The inner plate has an opening for mounting dial keys which extend out of the front panel through corresponding openings provided on the front panel. An intermediate reinforced plate is interposed between the inner surface of the front panel and the inner plate, having a reinforced section on which an opening for the dial keys is formed.
