During installation, one end of the inner ejector rod 25 is installed in the first accommodating cavity 121, and then the stop piece is installed, so that one end of the stop piece extends into the first limiting groove 251, thereby fixedly connecting the inner ejector rod 25 and the clamp tongue 12 in the axial direction, and in the circumferential direction, the stop piece can be in rolling contact fit with the first limiting groove 251, so that the inner ejector rod 25 can be in rotary fit with the clamp tongue 12.
Further, as shown in fig. 2, for ease of installation, the first resilient member 26 and the second resilient member 24 are each preferably designed as a compression spring. In this design, the second elastic member 24 is sleeved on the inner push rod 25, and the first elastic member 26 is sleeved outside the inner push rod 25, the connecting cylinder 27 and the connecting ring 23.
Further, as shown in fig. 1 and 3, for convenience of operating the driving rod 21, the driving assembly 2 further includes a grip 22; the grip 22 is connected to the other end of the drive lever 21, and can be brought into contact with the operation lever 3. Of course, instead of this manual actuation, an electric mechanism may be provided for the manual actuation of the handgrip 22 to effect the electric actuation of the inner ram 25.
Furthermore, in order to break through the limiting conditions of the angle and the space angle of the cabinet body and realize dead angle-free operation, the application also designs a universal rotating mechanism 4; one end of the universal rotating mechanism 4 is connected with the chuck 1, and the other end is connected with one end of the operating rod 3. That is, the angle between the chuck 1 and the operating rod 3 can be adjusted at will by the universal rotating mechanism 4, so that the applicability is stronger.
Because of the design of the universal rotation mechanism 4, as shown in fig. 4, in order to ensure that the driving rod 21 can normally drive the inner ejector rod 25, one end of the driving rod 21 is connected with an elastic connecting rod 28, and the elastic connecting rod 28 is connected with the inner ejector rod 25. The two ends of the elastic connecting rod 28 can be fixedly connected with the driving rod 21 and the inner ejector rod 25 in a welding mode respectively, and a concave hole for the elastic connecting rod 28 to extend into can be formed in the bottom of the inner ejector rod 25, so that the reliability of connection is improved.
Further, as shown in fig. 1 and 4, the universal rotating mechanism further comprises an insulating protective rubber sleeve 5, and the protective rubber sleeve 5 is sleeved outside the universal connecting mechanism, so that a certain protective effect is achieved on the universal rotating mechanism 4, and the use is safer.
Further, as shown in fig. 4, in the case of the universal rotation mechanism 4 design, an upper crank 41, a lower crank 42, and an adjustor 43 are included.
One end of the upper crank handle 41 is connected with the chuck 1, the other end is hinged with one end of the lower crank handle 42, one end of the lower crank handle 42 is connected with one end of the operating rod 3, and the regulator 43 is connected with the lower crank handle 42 and the upper crank handle 41 and is used for regulating an included angle between the upper crank handle 41 and the lower crank handle 42. The adjuster 43 may be a screw fastener including a quincuncial screw or the like that passes through the portion of the upper handle 41 that is hingedly adjacent to the lower handle 42 to lock the rotational connection between the upper handle 41 and the lower handle 42 by rotation or to unlock the rotational connection between the upper handle 41 and the lower handle 42. The universal rotation mechanism 4 can directly adopt CN210318230U which is applied and authorized by my department and is a universal transmission rotation mechanism of a grounding rod, and therefore, the more specific structure composition of the universal rotation mechanism 4 is not repeated.
Further, as shown in fig. 4, the application further comprises a locking element 6, wherein the chuck 1 is rotatably connected with the operation rod 3, and the locking element 6 is used for locking the rotation connection between the chuck 1 and the operation rod 3. It can be appreciated that the locking piece 6 is designed, so that the chuck 1 can be installed on the operating rod 3 in a manner of adjusting the rotation angle, and the applicability is further improved.
Further, the clamp 11 may be provided with a protruding portion 113, and the mounting cavity 112 is formed on the protruding portion 113, so that the design of the protruding portion 113 is beneficial to the forming of the mounting cavity 112, and the protruding portion 113 may be integrally formed.
Furthermore, the design of the protruding shaft portion 113 is also convenient to realize the design of adjustable rotation angle.
Taking the universal rotation mechanism 4 as an example, the upper crank handle 41 may be provided with a second accommodating cavity 411 for the protruding shaft 113 to extend into; the lock piece 6 is inserted on the peripheral surface of the upper crank handle 41 and is in threaded connection with the upper crank handle 41; one end of the lock 6 extending into the upper lever 41 abuts against the boss portion 113. The locking piece 6 can be a threaded fastener such as a butterfly screw, and the locking piece 6 is rotated until the locking piece is not abutted against the protruding shaft portion 113, at the moment, the chuck 1 can be driven to rotate, and after the chuck is rotated to a proper angle, the locking piece 6 is rotated until the chuck is abutted against the protruding shaft portion 113, so that the chuck 1 is fixed, and the angle adjustment is completed.
If the universal rotation mechanism 4 is not provided, the second accommodating chamber 411 may be provided on one end of the operation lever 3.
In this design, as shown in fig. 2, the protruding portion 113 may further be provided with a second limiting groove 114, and the locking member 6 may extend into the second limiting groove 114 and then abut against the protruding portion 113. In this way, even if the lock 6 does not abut against the protruding portion 113, the protruding portion 113 can be restrained in the axial direction by the engagement with the second restraining groove 114, so that the chuck 1 is prevented from coming out, and the connection engagement is more reliable.
