The length of the length of second accommodating chamber 31 and the third accommodating chamber 32 is sequentially increased, so that the second accommodating chamber 31 is shunk
In the first accommodating chamber 30, third accommodating chamber 32 is shunk when the second accommodating chamber 31, and corresponding free end protrusion, third accommodates strong length
Setting have no effect on the plug of bolt, when the first guard assembly is contracted to most in short-term, cooperation is opened opening 10 and is formed for bolt
It is inserted in the space of three jacks 20, and when bolt plugs completely, bolt tip height is higher than the third accommodating chamber 32
Tip height, so that third accommodating chamber 32 abuts with the bolt and positions 32 position of third accommodating chamber；
Second guard assembly comprising:
Circular slab 8, top has annular protrusion 80 compatible with the sliding slot 22, so that the circular slab 8 passes through
Protrusion 80 with the sliding slot 22 cooperation is rotatably arranged 2 bottom surface of level board, through the circular slab 8 set there are three perforation；
Telescopic component 4 comprising the outer sleeve 40 being rotatably set in the accommodation groove 23,40 top of outer sleeve are high
Degree is lower than 2 apical side height of level board, and 40 bottom end of outer sleeve is fixedly arranged on the circular slab 8, in the outer sleeve 40
The transversal cross-section of side wall be it is non-circular, slided up and down in the outer sleeve 40 and be arranged with inner sleeve 41,41 top of inner sleeve
4th spring 42 is set between (one end far from the outer sleeve 40) and 40 bottom end of the outer sleeve, and 41 top of inner sleeve is hung down
Directly horizontal along stretching equipped with block 43 is held in the inner sleeve 41, there are two the receiving grippings for 2 top of the level board recess tool
The holding tank 25 of block 43, when the gripping block 43 is located in holding tank 25, the 4th spring 42 is in compressive state,
In, three perforation and two holding tanks 25 are arranged are as follows: when the gripping block 43 is located in one of holding tank 25, three perforation
Floor projection on level board 2 is not intersected with any jack 20, when the gripping block 43 is located at another holding tank 25, three
The floor projection perforated on level board 2 is Chong Die with three one-to-one correspondence of jack 20.
In the above-mentioned technical solutions, the top plate 12 is integrally formed with 1 top of shell, can be made by the opening 10
The jack 20 shows, and provides for bolt plug in being specifically arranged in the space of jack 20, lower cavity 21 according to existing three hole
The set-up mode of socket is equipped with, and the inner sleeve 41 and the outer sleeve 40 are rotatable relative to the accommodation groove 23, and
The inner sleeve 41 is non-rotatable relative to the outer sleeve 40, in use process, when not using socket, and described gripping block 43
In in one of holding tank 25, floor projection of three perforation on level board 2 is not intersected with any jack 20, i.e. circular slab
8 have blocked three jacks 20, and the free end of the third accommodating chamber 32 of the first guard assembly is connected to 1 inner sidewall of shell, i.e.,
The opening 10 is sealed, further avoids unnecessary and contacts；When using socket, compression third accommodating chamber 32 is accommodated towards first
30 direction of chamber is moved to the first guard assembly and is contracted to most short, and cooperation, which is opened opening 10 and formed, for bolt is inserted in two jacks 20
Space, while rotating grip block 43 and then circular slab 8 being driven to rotate, the gripping block 43 is made to be located at another holding tank 25, three
Floor projection of a perforation on level board 2 is Chong Die with three one-to-one correspondence of jack 20, i.e. rotating opening jack 20, and bolt plugs
In in jack 20, and third accommodating chamber 32 abuts with the bolt and positions 32 position of third accommodating chamber；Using this technical side
Case, by the setting of the first guard assembly, when elongation, blocks jack 20, and when contraction, which provides, is inserted in two jacks 20 for bolt
Space, without change actual application in bolt between jack 20 at a distance from, do not influence jack 20 itself use, realization nothing
The first floor of obstruction is protected, and cooperation the second guard assembly rotation three jacks 20 of synchronous protection realize the dual guarantor to Three-hole socket
Shield；And first guard assembly be extensible member, be contracted to most in short-term can by bolt cooperate fix, without fixed dress is additionally arranged
It sets, and the circular slab 8 of the second guard assembly is set to 2 lower section of level board, does not influence jack 20 use itself equally, it is whole to tie
Structure is simple and practical.
In another technical solution, the 23 side wall middle and lower part level of accommodation groove is recessed inwardly to form annular guide groove
24,40 lateral wall of outer sleeve, which outwardly protrudes, is equipped with guide pad 44 compatible with the guide groove 24.Using this scheme
Improve the stability of the second guard assembly rotation.
In another technical solution, the 12 bottom surface free end of top plate is downwardly protrude to form the second raised line 50, the water
Plate 2 is located at formation third raised line 51 protruding upward immediately below second raised line 50, the third raised line 51 and described second
Raised line 50 cooperatively forms the notch mobile for the second accommodating chamber 31, and second accommodating chamber 31 is close to first accommodating chamber 30 1
The top and bottom at end outwardly protrude to form the 4th raised line 52 respectively, and underlying 4th raised line, 52 bottom end is supported with the level board 2
It connects (a), 51 top of third raised line abuts (b) with the 31 lateral wall low side of the second accommodating chamber, and the 4th be located above is convex
52 top of item abuts (c) with 12 bottom surface of top plate, so that second accommodating chamber 31 sliding is set to first accommodating chamber 30
Interior, the 5th raised line 53 of the inwardly projecting formation in the top and bottom of 31 free end of the second accommodating chamber, two the 5th raised lines 53 cooperate shape
At the notch mobile for the first accommodating chamber 30, top and bottom of the third accommodating chamber 32 close to one end of second accommodating chamber 31
It outwardly protrudes to form the 6th raised line 54, underlying 5th raised line, 53 bottom end is supported with the 32 lateral wall low side of third accommodating chamber
