Detailed Description

The present invention is further described below with reference to fig. 1 to 4.

A manual clamp comprises two clamping arms, a fixing piece, a connecting column 203, a spring button 301 and a fixing shell 302. The connecting column 203 is arranged inside the fixed shell 302, and one end of the connecting column 203 is connected with the bottom of the fixed shell 302; the fixing piece comprises a first cylindrical section 201 and a second cylindrical section 204, one end of the second cylindrical section 204 is connected with the first cylindrical section 201, the diameter of the first cylindrical section 201 is smaller than that of the second cylindrical section 204, a platform is arranged at the joint of the two cylindrical sections conveniently, and fixation can be achieved on the platform. In order to connect the fixing member and the connecting column 203, a connecting cavity 205 is formed at the bottom of the second cylindrical section 204, and the other end of the connecting column 203 is sleeved in the connecting cavity 205; the connecting column 203 is sleeved with a spring 202, and two ends of the spring 202 respectively abut against the bottom surfaces of the fixed shell 302 and the second cylindrical section 204. The clamping arm comprises a first threaded rod 101, a clamping block 102, a first connecting arm 401 and a second connecting arm 402; the first connecting arm 401 is hinged to the second connecting arm 402, a fixing ring 403 is arranged on the first connecting arm 401, and the first threaded rod 101 is in threaded connection with the fixing ring 403. The clamping block 102 is fixedly mounted at one end of the first threaded rod 101, and a plurality of friction lugs are arranged on the side surface of the clamping block 102 and are abutted against a clamped workpiece. The friction lugs increase the friction between the clamp block 102 and the clamped workpiece, making the clamp arm clamp tighter. The distance between the two clamping blocks 102 can be adjusted by rotating the first threaded rod 101 so as to be suitable for clamping workpieces with different sizes. The two clamping arms respectively penetrate through the fixed shell 302 and are fixedly connected with the second cylindrical section 204 and are symmetrically distributed. In addition, the first connecting arms 401 of the two clamping arms are respectively hinged with the fixed housing 302, thereby giving a limited position to the clamping arm supporting point. In order to adjust the position of the clamp in the vertical direction, therefore, the spring button 301 is fixedly installed on the second cylindrical section 204, and the spring button 301 is configured with two limiting holes which are arranged on the fixed shell 302. In order to adjust the position of the clamp in the horizontal direction, the fixed housing 302 is slidably connected to the sliding seat, and the sliding seat drives the clamp to move as a whole. The sliding seat includes fixed slot 503, second threaded rod 501, has seted up threaded hole on the lateral wall of fixed slot 503, and second threaded rod 501 passes threaded hole and fixed slot 503 threaded connection, and second threaded rod 501's one end and fixed shell 302 bottom fixed connection, has seted up the sliding tray on the lateral wall of shell bottom, is equipped with protruding edge 503 on the fixed slot 503 inner wall, protruding edge 503 card locates in the sliding tray.

The use process of the manual clamp is as follows: when the fixing piece is pressed down manually, the spring 202 is compressed, the spring button 301 moves downwards along with the fixing piece until being clamped in the limiting hole, the position of the fixing piece can be limited, the clamping arm moves downwards along with the fixing piece, automatic tightening is achieved, and the clamping function is achieved. When the clamping arms need to be loosened, the spring button 301 can be retracted only by pressing the spring button 301 from the limiting hole, and the fixing piece can be lifted up in the past, so that the clamping arms can be loosened.

As can be seen from the above description, the device has the following advantages: the problem of trachea winding carousel has been avoided in this anchor clamps use on the carousel, in addition, through the mode of manual pressing, drives the arm lock and presss from both sides tightly by the clamp work piece, then makes spring button pop out through pressing down spring button, and the arm lock resumes to open and relaxs the state, and it is very convenient to operate like this. And the clamping block is provided with a friction lug, so that the friction between a clamped workpiece and the clamping arm is enhanced, and the clamping can be more tightly realized.
