DETAILED DESCRIPTION

[0026] The specific implementation of the utility model is described in detail below with reference to the accompanying drawings.

[0027] Reference Figure 1 and Figure 2 , 3 The utility model provides a detachable plastic wrench for a hose, comprising a first component 1 and a second component 2, characterized in that: the first component 1 and the second component 2 are connected in combination by two connecting pieces 3, the side wall of the first component 1 is provided with two semi-annular track grooves 1 4, the side wall of the second component 2 is provided with two semi-annular track grooves 2 5, the semi-annular track grooves 1 4 and the semi-annular track grooves 2 5 have the same size and structure, a slider 6 is slidably sleeved in the two semi-annular track grooves 1 4, one side of the two sliders 6 is fixedly connected with a notch paddle 7, the side walls of the first component 1 and the second component 2 are provided with ratchet teeth 9, the inner wall of the notch paddle 7 is fixedly connected with a limiting mechanism 8, and the limiting mechanism 8 cooperates with the ratchet teeth 9 to limit the notch paddle 7 from rotating along the first component 1 and the second component 2;

[0028] The connecting member 3 includes a first connecting block 31 and a second connecting block 33. The first connecting block 31 and the second connecting block 33 are fixedly connected to the side walls of the first component 1 and the second component 2 respectively. The inner sides of the first connecting block 31 and the second connecting block 33 are respectively provided with matching plug-in blocks 32 and slots 34. The top and bottom of the second connecting block 33 are both provided with column holes connected to the slots 34. The two column holes are fixedly connected with locking mechanisms 35. The top and bottom of the plug-in block 32 are both provided with pin holes matching the locking mechanism 35.

[0029] Reference Figure 2 There are two ratchets 9 on the side walls of the first component 1 and the second component 2, and there are two limiting mechanisms 8. When the plastic wrench is driven to rotate and tighten the object by turning the notched paddle 7, the limiting mechanism 8 is subjected to a large force. By setting two corresponding limiting mechanisms 8 and ratchets 9, the pressure on a single limiting mechanism 8 is reduced and the service life is increased.

[0030] Reference Figure 4 The locking mechanism 35 includes a fixing ring 351, which is fixedly connected in the column hole of the second connecting block 33. A threaded rod 352 is movably sleeved in the inner cavity of the fixing ring 351, and a sleeve 353 is threadedly sleeved on the side wall of the threaded rod 352. The sleeve 353 is adapted to the pin hole of the plug block 32. During operation, the sleeve 353 is moved downward by rotating the threaded rod 352 under the influence of the threaded structure. When the sleeve 353 enters the slot 34 and is inserted into the pin hole of the plug block 32, the plug block 32 is locked in the slot 34.

[0031] Reference Figure 4A positioning strip is provided on the side wall of the sleeve 353, and a positioning groove matching the positioning strip is provided in the column hole of the second connecting block 33 and the pin hole of the insert block 32. The positioning strip slides in the positioning strip and fits in the positioning strip. The positioning strip cooperates with the positioning groove, so that the sleeve 353 can be prevented from rotating with the threaded rod 352 due to friction.

[0032] Reference Figure 4 The side wall of the threaded rod 352 is provided with an annular groove 354, and the fixing ring 351 is movably sleeved in the annular groove 354. This arrangement can limit the vertical displacement of the threaded rod 352, thereby preventing the threaded rod 352 from falling off from the inner cavity of the fixing ring 351.

[0033] Reference Figure 5 The limiting mechanism 8 includes an outer solid shell 81, and a moving block 82 is slidably sleeved inside the outer solid shell 81. The end of the moving block 82 away from the ratchet 9 is transmission-connected to the inner wall of the outer solid shell 81 through a spring 83. The end of the moving block 82 facing the ratchet 9 is set as a slope a. When the recessed pick 7 is toggled clockwise, the ratchet 9 contacts the slope a of the moving block 82 and generates a resisting force on the slope a. Under the action of the slope a, the moving block 82 can be retracted into the inner part of the outer solid shell 81, and under the influence of the elastic force of the spring 83, the moving block 82 can enter another tooth groove from one tooth groove of the ratchet 9, thereby the recessed pick 7 can be rotated along the plastic wrench. When the recessed pick 7 is toggled counterclockwise, one side of the moving block 82 is resisted by the inner wall of the tooth groove of the ratchet 9, thereby limiting the counterclockwise rotation of the recessed pick 7, thereby achieving the effect of the recessed pick 7 driving the plastic wrench to rotate.

[0034] Reference Figure 5 , 6 An anti-slip component 84 is provided inside the outer solid shell 81, and the anti-slip component 84 is connected to the moving block 82. The anti-slip component 84 is composed of a connecting rod 841 and a positioning plate 842. A cylindrical groove is provided inside the moving block 82, and the positioning plate 842 is slidably sleeved in the cylindrical groove. One end of the connecting rod 841 is fixedly connected to the inner wall of the outer solid shell 81, and the other end penetrates into the cylindrical groove and is connected to the positioning plate 842. The diameter of the positioning plate 842 is larger than the diameter of the connecting rod 841. When the moving block 82 moves to the outside of the outer solid shell 81, the moving distance of the moving block 82 is limited by the anti-slip component 84, thereby preventing the moving block 82 from falling off from the inside of the outer solid shell 81.

[0035] Reference Figure 7 The cross-sections of the semi-annular track groove 4 and the slider 6 are T-shaped, which can prevent the slider 6 from falling off from the interior of the semi-annular track groove 4.

[0036] The working principle of the utility model is as follows: when in use, the first component 1 and the second component 2 are combined around the hose to form a plastic wrench. The process is to first close the first component 1 and the second component 2 so that the plug 32 enters the slot 34 of the second connecting block 33, and then the locking mechanism 35 is connected with the pin hole on the plug 32 to complete the locking operation, thereby completing the combination process of the first component 1 and the second component 2;

[0037] After the combination is completed, the semi-annular track groove 1 4 on the first component 1 and the semi-annular track groove 2 5 on the second component 2 are completely combined to form a complete annular track groove, and the ratchet teeth 9 on the first component 1 and the second component 2 are combined to form a whole. At this time, the slider 6 can perform annular movement in the semi-annular track groove 1 4 and the semi-annular track groove 2 5. The slider 6 is connected with the notched pick 7 so that the notched pick 7 can be rotated in annular manner along the plastic wrench. The limiting mechanism 8 cooperates with the ratchet teeth 9 to limit the rotation direction of the notched pick 7 so that it can only be rotated in one direction. Therefore, when the notched pick 7 is moved in the limited direction, the annular wrench can be rotated to tighten the object, and the notched pick 7 can achieve a lever effect, making the process of tightening the object more labor-saving.

[0038] According to the above structural relationship, when the device is used in a narrow space, the operation is limited. At this time, it is only necessary to slightly move the recessed pick 7 to tighten the object, and then to reversely move the recessed pick 7 to make it rotate along the plastic wrench to reset. During this process, the recessed pick 7 does not drive the plastic wrench to rotate. In this way, the recessed pick 7 can be moved back and forth at a small angle to realize the operation of tightening the object with the plastic wrench, thereby solving the problem of inconvenient operation in a narrow space.

[0039] The above shows and describes the basic principle, main features and advantages of the utility model. The utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. The utility model may have various changes and improvements without departing from the spirit and scope of the utility model. These changes and improvements fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
