Abstract: A tree pruner includes a hook set, a blade pivotally mounted on the hook set, a main linkage pivotally connected to the hook set, an auxiliary linkage set pivotally connected to the main linkage and the blade, a first pulley mounted to the main linkage, a second pulley mounted to the hook set and a rope coiling the two pulleys. The auxiliary linkage set has a first linkage and a second linkage pivotally connected to each other for elongating a lever arm from the main linkage.

Abstract: A protection device for a sprinkler is connected between two rods of the sprinkler and includes two recessed support areas which are located beneath two extreme positions of a travel trace of the pivotable tube of the sprinkler. When the pivotable tube is pressed by a load, the pivotable tube is supported by either of the two recessed support areas so as to protect the gear mechanism from being damaged.

Abstract: A hose includes a central tube located at a center of the hose and a plurality of ribs are connected between the central tube and an inner periphery of the hose so as to define multiple second passages between the central tube and the inner periphery of the hose. The hose includes a circular cross section and is conveniently connected with existed spray nozzles or sprinklers.

Abstract: A hose assembly includes a connection sleeve and a connection member 20 rotatably received in the connection sleeve. The connection sleeve has a first flange extending from an inner periphery thereof and a second flange extends from an outer periphery of the connection member so that an underside of the first flange is overlapped on the second flange. An annular lip extends outward from an outer periphery of an end of the connection member and is rested on a top of the first flange. The handle includes a connection end with outer threaded periphery for being connected with a watering nozzle.

Abstract: A hose assembly includes a connection sleeve which is rotatably mounted to a connection member which is connected to a hose. The connection sleeve has a first flange extending from an inner periphery thereof and a positioning hole is defined radially through a wall of the connection sleeve. The connection member has a second flange extending from an outer periphery thereof so as to be engaged with the first flange. A positioning groove is defined in the outer periphery of the connection member and a positioning member extends through the positioning hole and is engaged with the positioning groove so that the connection sleeve is rotatable relative to the connection member.

Abstract: A hose connection device includes a handle and a first flange extends from an inner periphery of the through hole of the handle. A connection member has a axial passage and a second flange extends from an outer periphery thereof. The connection member is inserted in the through hole and the first flange is overlapped on the second flange. A nut is received in the through hole and threadedly mounted to the connection member so that the connection member is independently rotatable relative to the handle. The handle includes a connection end with outer threaded periphery for being connected with a watering nozzle.

Abstract: An upright heating burner having a heatsink device includes an upright stand, an upright tube, a burner, an air guide cylinder, and a heatsink device. The heatsink device is mounted on a top of the air guide cylinder and includes an annular support seat, a shaft, and a fan unit. Thus, the fan unit is driven by the heated air to rotate on the shaft automatically, so as to diffuse the heated air outward wholly and completely, thereby efficiently achieving the heatsink effect.

Abstract: A hose supporting spool device includes a spool rotatably secured to a support device for winding a hose, a shaft secured to the support device and having a passage, a block formed on the shaft and having a peripheral slot and one or more grooves communicating the peripheral slot of the block with the passage of the shaft. A housing is rotatably engaged onto the block and the shaft and has a mouth coupled to a water reservoir. Two gaskets are engaged on the sides of the block and have curved recesses for receiving the curved outer portions of the block.

Abstract: A shovel includes a base panel portion, a shovel member secured on the base panel, a handle secured to the shovel member, and a blade secured to the bottom and front portion of the base panel and extended forward beyond the base panel for engaging with material such as the snow. The shovel member and the base panel may be made of lighter metal or plastic or composite materials, for decreasing the weight of the shovel and for reducing the manufacturing cost for the shovel. The blade is made of stronger metal materials for increasing the working life of the shovel.

Abstract: A sprinkler includes a pipe having a number of outlet openings for outward flow of the water, and a number of rings rotatably engaged on the pipe and each having an orifice for selectively aligning with the outlet opening of the pipe and for selectively blocking the outlet opening, such that the outlet openings of the pipe may be selectively opened or blocked by the rings. A housing is engaged on the pipe and has a number of apertures for slidably receiving the actuating ears of the rings to limit the movement of the ring relative to the pipe.

Abstract: A sprayer gun includes a handle and a valve stem slidably received in the rear portion. A stop is secured to the valve stem and engaged with the handle, and has one or more ratchet teeth. A spring lever has one end secured to the handle and has a number of ratchet teeth for engaging with the ratchet teeth of the stop and for preventing the stop from being moved forward relative to the spring lever. The water is thus allowed to continuously flow out of the sprayer gun without continuously depressing the control hand grip toward the handle by the the ratchet teeth.

Abstract: A sprayer device includes a tube extended from a sprayer member and a hose coupling the tube to a water reservoir. A pipe is slidably engaged on the hose and the tube. A control ferrule is engaged on the pipe and has an inclined inner peripheral surface for adjustable forcing and securing the pipe to the tube. One or more conduits may further be adjustably secured to the pipe. The pipe and the conduit may be easily and quickly adjusted relative to the tube and the pipe respectively and will not affect the water tight seal between the hose and the tube.

Abstract: A sprayer includes a housing rotatably secured onto a front portion of a handle. The housing has a peripheral wall and a peripheral partition and has a number of ports formed by a number of barrels. A cover is secured to the rear of the housing and engaged with the peripheral partition and has one or more slots. The barrels include an end extended beyond the peripheral partition and engaged into the slot of the cover for solidly securing the cover to the housing. The slot of the cover may be a curved slot for receiving two or more barrels.
