[0033] See also Figure 1 , Figure 2 and Figure 4 A novel fast disassembly and assembly transmission chain clamp comprises a device shell 1, a threaded hole 3 is provided at the front and rear ends of the middle and upper part of the outer wall of the device shell 1, a first clamping column 4 is provided inside the threaded hole 3, a first external thread 5 is provided on the outer wall of the first clamping column 4, the first clamping column 4 is threadedly connected to the threaded hole 3, a clamping block 6 is fixedly connected to the end of the first clamping column 4, a connecting block 11 is provided at the left and right ends of the front side of the outer wall of the device shell 1, a connecting rod 7 is fixedly connected to the outer wall of the connecting block 11, a top end of the connecting rod 7 is provided with an ejection assembly, and a sliding mechanism 2 is provided on the outer side of the connecting block 11;

[0034] Specifically, the ejection assembly includes an external sleeve 8, which is fixedly connected to the top of the connecting rod 7, a second abutting column 9 is arranged inside the external sleeve 8, a second external thread 10 is arranged on the outer wall of the second abutting column 9, and the second abutting column 9 and the external sleeve 8 are threadedly connected; a connecting column 12 is fixedly connected to the outer wall of the second abutting column 9, and a plurality of rotating columns 13 are fixedly connected to the outer wall of the connecting column 12 at equal intervals;

[0035] Furthermore, by the operator rotating the first clamping column 4, the clamping block 6 can be driven to clamp the chain placed on the top wall of the equipment shell 1, thereby facilitating the operator to disassemble the chain, and by rotating the rotating column 13, the second clamping column 9 can be controlled to push out or push in the chain pin of the chain, thereby achieving the effect of disassembly and assembly; at the same time, a finger groove 17 is opened at the end of the outer wall of the first clamping column 4 to increase the friction force of rotation, thereby facilitating the operator to rotate the first clamping column 4.

[0036] See also Figure 1 , Figure 3 and Figure 5 The sliding mechanism 2 includes two first device grooves 201, which are respectively opened at the left and right ends of the front side of the outer wall of the device shell 1, and the first device groove 201 has a sliding groove 202, and the connecting block 11 is slidably connected to the inside of the sliding groove 202;

[0037] Specifically, the left and right ends of the bottom wall of the device shell 1 are provided with second device grooves 15, and the inner wall of the second device groove 15 is fixedly connected with a magnetic block 16; the outer wall of the device shell 1 is set as a curved surface; the outer wall of the abutting block 6 is provided with a card slot 14;

[0038] Furthermore, the chain can be assembled and disassembled at different positions by sliding the connecting rod 7 inside the sliding groove 202, thereby improving the convenience of the device; a second device groove 15 is opened at the left and right ends of the bottom wall of the device shell 1, and the magnetic block 16 is fixed inside the second device groove 15, so that for those chains that have been installed on the equipment, the clamp can be adsorbed on the equipment through the magnetic block 16, and then the chain can be assembled and disassembled, so the magnetic block 16 needs to have a strong magnetic force to ensure the stability of the clamp; the outer wall of the device shell 1 is set to a curved surface to prevent people from accidentally hitting the sharp corners of the clamp and causing injuries; a card slot 14 is opened on the outer wall of the tightening block 6 to increase the friction between the chain and the card slot 14, and to perform a certain degree of engagement, thereby further improving the stability of the chain.

[0039] Working principle: When the transmission chain needs to be assembled or disassembled, the chain is placed on the top wall of the equipment shell 1. Threaded holes 3 are opened in the middle of the front and rear ends of the outer wall of the equipment shell 1. By rotating the first clamping column 4, the first clamping column 4 can be controlled to drive the clamping block 6 to move, so that the chain can be positioned and clamped. Connecting rods 7 are set at the left and right ends of the front side of the outer wall of the equipment shell 1. The top of the connecting rod 7 is fixed with an external sleeve 8. The operator can control the second clamping column 9 and the external sleeve 8 to transmit the thread by rotating the rotating column 13, and can control the second clamping column 9 to move forward and backward, so that the chain pin of the chain can be pushed out or pushed in, thereby achieving the purpose of disassembling and assembling the chain. 9 needs to push out the chain pin, and most of the chain pins are made of metal, so the second clamping column 9 needs to have a certain pressure resistance and hardness to ensure that it will not cause too much wear after a long period of work. At the same time, the connecting rod 7 is designed to be adjustable. Since the chain sizes are different, it is necessary to control the second clamping column 9 to push out the chain pin by adjusting the height of the connecting rod 7, and by opening the first device groove 201 at the left and right ends of the front side of the outer wall of the device shell 1, and opening the sliding groove 202 on the inner wall of the first device groove 201, the connecting block 11 can be controlled to slide in the sliding groove 202, and the chain can be disassembled and assembled at different positions by adjusting the position of the connecting rod 7, thereby improving the convenience and practicality of the device.

[0040] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto.
