[0034] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0035] This embodiment provides a PVC casing opening device, such as Figure 1 As shown, it includes: a positioning block 1, a guide rod 2, a support 3, a guide seat 4 and a blade 5;

[0036] The positioning block 1, the support 3 and the guide seat 4 are arranged on the substrate 6. The positioning block 1 and the guide seat 4 are respectively arranged at both ends of the support 3. The positioning block 1 can adjust the position on the substrate 6. Figure 4 As shown, a concave arc groove 401 is provided on the top of the guide seat 4;

[0037] The guide rod 2 is arranged on the top of the support 3. Figure 2 and Figure 3As shown, the diameter of the end of the guide rod 2 away from the positioning block 1 gradually decreases to form a guide portion 201, and the guide portion 201 is located above the arc groove 401. A cutting space is formed between the guide portion 201 and the arc groove 401, and the blade 5 is arranged in the cutting space. Figure 5 The cutting edge 501 of the blade 5 shown is facing the side of the guide seat 4 away from the positioning block 1;

[0038] The PVC casing opening device provided in this embodiment effectively prevents the blade 5 from being exposed by arranging the blade 5 in the cutting space between the guide portion 201 and the arc groove 401, thereby reducing the risk of scratches on operators.

[0039] By providing the guide portion 201 and the arc groove 401 to guide the sleeve, the operator only needs to pull the sleeve to accurately open the blade 5 in the cutting space of the sleeve, effectively avoiding the deviation of the opening;

[0040] By arranging a positioning block 1 with an adjustable position on the base plate 6, the length of the sleeve pulled by the operator is limited, thereby accurately controlling the opening length.

[0041] In a specific embodiment, Figure 1 As shown, the positioning block 1 is provided with a positioning block threaded hole 101, and the substrate 6 is provided with a plurality of through holes arranged along the length direction of the substrate 6. By screwing the bolts passing through the through holes, the bolts are threadedly connected with the positioning block threaded holes 101 to achieve the fixation of the positioning block 1 on the substrate 6. By setting a plurality of through holes arranged along the length direction of the substrate 6, the positioning block 1 can adjust its position on the substrate 6.

[0042] In a specific embodiment, Figure 6 As shown, the top of the support 3 is provided with a transition portion 301, and the width of the transition portion 301 gradually increases from the end close to the guide seat 4 to the end close to the positioning block 1 (as shown in FIG. Figure 7 and Figure 8 As shown, L1 is smaller than L2), so that the sleeve after opening can pass through the support 3 smoothly.

[0043] In a specific embodiment, the guide seat 4 is detachably connected to the base plate 6, and the guide rod 2 is detachably connected to the support 3, so as to adapt to sleeves of different diameters by replacing the guide seat 4 and the guide rod 2;

[0044] In this embodiment, if Figure 3 As shown, the guide rod 2 is provided with a guide rod through hole 205. Figure 6 As shown, the support 3 is provided with a first support threaded hole 302 and a second support threaded hole 303. Figure 4 As shown, the guide seat 4 is provided with a guide seat threaded hole 403;

[0045] The guide rod 2 is detachably connected to the support 3 by screwing the bolt passing through the guide rod through hole 205 to make it threadedly connected to the first threaded hole 302 of the support;

[0046] The base plate 6 is provided with a through hole corresponding to the threaded hole 403 of the guide seat, and a bolt passing through the through hole corresponding to the threaded hole 403 of the guide seat is threadedly connected with the threaded hole 403 of the guide seat, thereby realizing a detachable connection of the guide seat 4 on the base plate 6;

[0047] The base plate 6 is provided with a through hole corresponding to the second threaded hole 303 of the support. By screwing a bolt passing through the through hole corresponding to the second threaded hole 303 of the support, it is threadedly connected with the second threaded hole 303 of the support, thereby realizing a detachable connection of the support 3 on the base plate 6.

[0048] In a specific embodiment, Figure 2 As shown, the guide rod 2 is provided with a positioning slot 204, and the transition portion 301 can be inserted into the positioning slot 204, so that the guide rod 2 and the support 3 can be quickly positioned during installation.

[0049] In a specific embodiment, Figure 1 As shown, the substrate 6 is provided with a scale 601, and the scale 601 is arranged along the length direction of the substrate 6. The operator can quickly confirm the position of the positioning block 1 on the substrate 6 through the scale 601 according to different opening length requirements, which is convenient for adjusting the position of the positioning block 1.

[0050] In a specific embodiment, Figure 2 As shown, the guide portion 201 is provided with a first socket 202 and a guide rod threaded hole 203. Figure 4 As shown, the arc groove 401 is provided with a second socket 402, and the two ends of the blade 5 are respectively inserted into the first socket 202 and the second socket 402;

[0051] The threaded hole 203 of the guide rod is used to install a fastening screw. By screwing the fastening screw, the fastening screw can press the portion of the blade 5 inserted into the first socket 202 , so that the blade 5 and the guide portion 201 are reliably fixed.

[0052] In actual operation, after determining the opening length of the sleeve, the operator confirms the installation position of the positioning block 1 on the substrate 6 through the scale 601, and then fixes the positioning block 1, puts the sleeve on the guide part 201 and pulls the sleeve so that the sleeve is cut by the cutting edge 501, and then continues to pull the sleeve until the end of the sleeve abuts the positioning block 1 to complete the opening of the sleeve.

[0053] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
