The size of the protective cover 206 is preferably extended to the bottom end of the rotating arm 202, so that when the operator holds the holding hole 207, the fingers of the operator will not contact the saw blade 205, but will contact the outer wall of the protective cover 206, thereby improving the personal safety of the operator.

[0034] Continuing to refer to the drawings Figure 1 and the drawings Figure 2 As shown, the cover assembly 300 is arranged on the table top 102 at the input end side of the cutting groove 103, that is, on the side of the table top 102 away from the electric saw blade cutting assembly 200, and the cover assembly 300 is used to outwardly eject the steel pipe 20 placed therein during cutting.

[0035] Specifically, the cover assembly 300 comprises a cover and a pair of guide roller assemblies, the cover comprises a top plate 301 and a pair of side plates 302, the top plate 301 is horizontally arranged above the table top 102, the pair of side plates 302 are symmetrically arranged on opposite sides of the top plate 301 along a conveying direction of the steel pipe 20, top ends of the side plates 302 are fixedly connected with outer side edges of the top plate 301, bottom ends of the side plates 302 are fixedly installed on top ends of the table top 102, so that the cover and the table top 102 form a containing space 303 for placing the steel pipe 20. As shown in Figs. 3 and 4, the containing space 303 is similar to a box-shaped structure, opposite ends of the containing space 303 along a steel pipe insertion direction are open, so that the steel pipe 20 can be inserted into the containing space 303 from one end and extended out of the containing space 303 from the other end. Figure 3 As shown in Figs. 3 and 4, the containing space 303 is similar to a box-shaped structure, opposite ends of the containing space 303 along a steel pipe insertion direction are open, so that the steel pipe 20 can be inserted into the containing space 303 from one end and extended out of the containing space 303 from the other end.

[0036] As shown in Figs. 3 and 4, the containing space 303 is similar to a box-shaped structure, opposite ends of the containing space 303 along a steel pipe insertion direction are open, so that the steel pipe 20 can be inserted into the containing space 303 from one end and extended out of the containing space 303 from the other end. Figure 1 As shown in Figs. 3 and 4, the containing space 303 is similar to a box-shaped structure, opposite ends of the containing space 303 along a steel pipe insertion direction are open, so that the steel pipe 20 can be inserted into the containing space 303 from one end and extended out of the containing space 303 from the other end. Figure 2 As shown in Figs. 3 and 4, the containing space 303 is similar to a box-shaped structure, opposite ends of the containing space 303 along a steel pipe insertion direction are open, so that the steel pipe 20 can be inserted into the containing space 303 from one end and extended out of the containing space 303 from the other end.

[0037] As shown in Figs. 3 and 4, the containing space 303 is similar to a box-shaped structure, opposite ends of the containing space 303 along a steel pipe insertion direction are open, so that the steel pipe 20 can be inserted into the containing space 303 from one end and extended out of the containing space 303 from the other end. Figure 1 As shown in Figs. 3 and 4, the containing space 303 is similar to a box-shaped structure, opposite ends of the containing space 303 along a steel pipe insertion direction are open, so that the steel pipe 20 can be inserted into the containing space 303 from one end and extended out of the containing space 303 from the other end. Figure 2 As shown in Figs. 3 and 4, the containing space 303 is similar to a box-shaped structure, opposite ends of the containing space 303 along a steel pipe insertion direction are open, so that the steel pipe 20 can be inserted into the containing space 303 from one end and extended out of the containing space 303 from the other end. Figure 5As shown, in some embodiments, one guide roller assembly includes a plurality of fixed guide rollers 307 rotatably mounted on one side of the accommodating space 303, and another guide roller assembly includes a pair of sliding blocks 306 and a plurality of sliding guide rollers 308. The cover and the table 102 are respectively provided with a plurality of inclined sliding grooves 305 on the other side relative to the fixed guide rollers 307. The inclined sliding grooves 305 are holes inclinedly extending from the other side of the cover to one side of the cutting groove 103. Similarly, the inclined sliding grooves 305 on the table 102 are consistent with the inclined sliding grooves 305 on the cover in terms of hole direction, and the number and position of the two are corresponding. The top end of the sliding guide roller 308 extends outwardly from the inclined sliding groove 305 and is rotatably mounted at the bottom end of the sliding block 306. One sliding block 306 is slidingly mounted on the upper end surface of the cover, and the other sliding block 306 is slidingly mounted on the bottom end of the table 102. The sliding block 306 on the cover is connected with the electric saw blade cutting assembly 200 through the connecting assembly 400. When the saw blade 205 in the electric saw blade cutting assembly 200 swings downward, the connecting assembly 400 drives the sliding guide roller 308 to move to the side of the fixed guide roller 307, thereby realizing the clamping function of the steel pipe 20. By adopting the linkage structure composed of the electric saw blade cutting assembly 200 + the connecting assembly 400 + the sliding guide roller 308, when the electric saw blade cutting assembly 200 is not pressed downward, the gap distance between the sliding guide roller 308 and the fixed guide roller 307 is in the maximum state, and at this time, the steel pipe 20 can be conveniently and smoothly inserted into the accommodating space 303. When the electric saw blade cutting assembly 200 is pressed downward for cutting, the electric saw blade cutting assembly 200 drives the sliding guide roller 308 to move to the side of the fixed guide roller 307 through the linkage assembly, and the steel pipe 20 is clamped, which can prevent the steel pipe 20 from shaking left and right during cutting.

[0038] Referring to the drawings Figure 3 As shown, in order to facilitate the movement of the steel pipe 20 in the accommodating space 303, guide rollers 304 are rotatably installed at the front and rear ends of the accommodating space 303. Thus, during the movement of the steel pipe 20 into or out of the accommodating space 303, the steel pipe 20 and the guide rollers 304 are in rolling contact, so that the movement of the steel pipe 20 is more smooth and unobstructed.

[0039] Referring to the drawings Figure 1 , the drawings Figure 4 , and the drawings Figure 6As shown, specifically, the connecting assembly 400 comprises a steel wire 402, a compression spring 403 and a guide wheel 401, a blind hole 3061 extending to the other side surface is formed at the top end of the sliding block 306 near one side of the cutting groove 103, the guide wheel 401 is rotatably installed on the cover near one side of the cutting groove 103, one end of the steel wire 402 is fixedly installed at the bottom end of the blind hole 3061 through the compression spring 403, and the other end of the steel wire 402 is fixedly connected with the electric saw blade cutting assembly 200 through winding on the guide wheel 401.

[0040] The electric saw blade cutting assembly 200 further comprises a base 201 fixedly installed on the table top 102, the base 201 is hingedly connected with one end of a rotating arm 202, the other end of the rotating arm 202 is fixedly installed with a motor 204, the output end of the motor 204 is fixedly connected with a saw blade 205, and the other end of the steel wire 402 is fixedly installed at one end of the rotating arm 202 (i.e. the end of the rotating arm 202 hingedly installed on the base 201). During the process of driving the rotating arm 202 to move downward, the end of the rotating arm 202 connected with the steel wire 402 moves upward, the upward moving steel wire 402 stretches the compression spring 403 and drives the sliding block 306 on the cover to move forward, but since the sliding block 306 on the cover is slidably installed in the inclined sliding groove 305 through the sliding guide roller 308, the sliding block 306 on the cover drives the sliding guide roller 308 to move along the inclined sliding groove 305 to the side of the fixed guide roller 307 (see FIG. 6), and since the bottom end of the sliding guide roller 308 is connected with the sliding block 306 at the bottom end of the table top 102, the sliding sliding guide roller 308 also synchronously drives the sliding block 306 at the bottom end of the table top 102 to move synchronously, thereby realizing clamping of the steel pipe 20; when the saw blade 205 completes the fixed-length cutting of the steel pipe 20, the operator releases the rotating arm 202, the end of the rotating arm 202 hingedly installed on the base 201 moves downward, the steel wire 402 is in a relaxed state at this time, and since the compression spring 403 is in a stretched state, the compression spring 403 is contracted and reset due to the stretching force of the steel wire 402 at this time, the compression spring 403 in the contracted state further drives the steel wire 402 to contract and reset, the steel wire 402 further drives the sliding block 306 to move to the side of the compression spring 403, the sliding block 306 reversely slides and resets along the inclined sliding groove 305, the sliding guide roller 308 gradually moves away from the fixed guide roller 307, the gap between the sliding guide roller 308 and the fixed guide roller 307 gradually increases, and this facilitates smooth forward movement of the subsequent steel pipe 20 for re-cutting.
