The first linkage is rotatably connected to the base, and includes a first rod portion and a second rod portion extending from the first rod portion. The second linkage includes a third rod portion and a fourth rod portion extending from the third rod portion. The third rod portion rotatably connects with the first rod portion. The fourth rod portion rotatably connects with the rotating portion of the clamping block.

Abstract: A clamping mechanism includes a positioning member, a support plate, a frame, a fastening assembly, and an operating assembly. The support plate defines a through hole. The fastening assembly is fixed to the frame. The fastening assembly includes a fastening member and an elastic member. The positioning member extends through the through hole of the support plate, and is fastened by the fastening member under an elastic force of the elastic member. The operating assembly resists the fastening member, thereby driving the fastening member away from the positioning member.

Abstract: A positioning apparatus includes a base plate and a deflection mechanism mounted upon the base plate. The deflection mechanism includes a stationary platform, a rocker assembly and a deflection platform. The stationary platform is mounted over the base plate for placing and positioning a workpiece. The deflection platform is tiltably mounted over the stationary platform via the rocker assembly and the height of the stationary platform itself is adjustable. The rocker assembly comprises a first rocker and a second rocker of different lengths.

Abstract: A screwdriver head mounting structure includes a mounting base, a screwdriver head, a latching member and an elastic member. The mounting base defines a mounting hole and an eccentric latching hole communicating with and positioned eccentric to the mounting hole. The screwdriver head is detachably assembled to the mounting base. The screwdriver head has a latching end inserted into the mounting hole of the mounting base. The latching member is releasably and adjustably assembled to the mounting base together with the elastic member. The latching member passes through the eccentric latching hole and latches with the latching end of the screwdriver head.

Abstract: A control valve includes a valve body, a valve plug, two adjusting elements and two operating members. The valve body has a valve hole defined through the valve body and further defines an inlet hole and two outlet holes respectively communicating with the valve hole. The valve plug is movably assembled within the valve body. Two ends of the valve plug are respectively exposed to the outside of the valve body. The two adjusting elements are respectively mounted to two ends of the valve body and respectively adjustably resist against two ends of the valve plug. The two operating members are respectively fixed to the two adjusting elements for driving the two adjusting elements to move the valve plug within the valve hole of the valve body, and thereby controlling the control valve to switch between an open state and a closed state.

Abstract: A clamping mechanism includes a base, a clamping block rotatably connected with the base, an eccentric handler and a guiding member. The eccentric handler defines a hinging hole and a sliding slot. Part of the sliding slot is eccentrically positioned relatively to the hinging hole. The eccentric handler hinges on the base via the hinging hole. The guiding member passes through the sliding slot and is movably connected with the clamping block. The eccentric handler pivots to enable and to force the guiding member to move along the sliding slot for clamping and releasing a workpiece placed on the base.

Abstract: A clamping assembly includes a base, a clamping block, a first linkage, and a second linkage. The clamping block includes a rotating portion and a clamping portion. The rotating portion is rotatably connected to the base. The clamping portion extends out from the rotating portion towards the base. The first linkage is rotatably connected to the base, and includes a first rod portion and a second rod portion extending from the first rod portion. The second linkage includes a third rod portion and a fourth rod portion extending from the third rod portion. The third rod portion rotatably connects with the first rod portion. The fourth rod portion rotatably connects with the rotating portion of the clamping block.

Abstract: A telescoping mechanism includes a base, a movable member, a support member, and a resisting assembly. The base defines a receiving groove. The movable member is slidably connected to and opposes the base. The support member is rotatably connected with the base. The support member includes a first support portion engaged in the receiving groove and a second support portion connected with the first support portion. The second support portion defines an engaging groove. The resisting assembly is mounted on the second support portion. To lift the movable member, the first support portion is lifted and resists against the movable member, and after the movable member is brought down to the base, the movable member latches in the engaging groove, and the resisting assembly resists against the movable member.

Abstract: A support mechanism includes a base, two guide poles positioned on the base, two guide poles positioned on the base, a support block slidably sleeved on the two guide poles, a V-shaped rod rotatably connected to a side of the base, a support rod rotatably connecting the V-shaped rod to the support block, and a L-shaped hook rotatably positioned on the V-shaped rod. The L-shaped hook comprises a support pole for supporting the support block.

Abstract: A clamping mechanism includes a positioning member, a support plate, a frame, a fastening assembly, and an operating assembly. The support plate defines a through hole. The fastening assembly is fixed to the frame. The fastening assembly includes a fastening member and an elastic member. The positioning member extends through the through hole of the support plate, and is fastened by the fastening member under an elastic force of the elastic member. The operating assembly resists the fastening member, thereby driving the fastening member away from the positioning member.

Abstract: A clamp mechanism includes a support plate, a frame, a positioning member, a resisting member, an operating assembly. The support plate defines an assembly hole. The frame is fixed to the support plate, and defines a positioning groove and a sliding groove. The positioning member extends through the assembly hole of the support plate, and received in the positioning groove. The operating assembly is connected to the resisting member. The resisting member is movably received in the sliding groove and opposite to the positioning member. The sliding groove has a first end adjacent to the positioning member and a second end away from the positioning member, such that the operating assembly drives the resisting member to move in the sliding groove from the second end to the first end, thereby clamping the positioning member in the positioning groove of the frame.
