Detailed Implementation The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0011] like Figure 1 As shown, a building decoration shovel includes a blade shell 1, with a handle 2 connected to one end of the blade shell 1. A slidable blade 4 is provided inside the blade shell 1. A push button 3 is provided on the handle 2. The push button 3 can move back and forth on the handle 2. The push button 3 is connected to the blade 4 through a pushing mechanism. Sliding the push button 3 backward can drive the blade 4 into the blade shell 1 to achieve storage. like Figure 2 , Figure 3 As shown, the front end of the blade housing 1 is provided with a detachable cover 101. The front end of the cover 101 is chamfered. The blade 4 passes through the cover 101. The cover 101 and the blade housing 1 are connected by bolts. Opening the cover 101 makes it easy to replace the blade 4. like Figure 6 As shown, the pushing mechanism includes a clamping block 5 that fixes the blade 4. The clamping block 5 slides in conjunction with the inner cavity of the blade shell 1. That is, the length and width of the clamping block 5 are exactly matched with the inner cavity of the blade shell 1. A pull rod 6 is connected to the rear end of the clamping block 5. The pull rod 6 is located inside the handle 2. A support column 601 is provided on the side wall of the pull rod 6. The push button 3 is connected to the support column 601.
[0012] The clamping block 5 is a U-shaped mechanism that holds the blade 4. Bolts are connected between the upper and lower ends of the clamping block 5. The bolts tighten the clamping block 5 so that the upper and lower sides clamp the blade 4. The bolts pass through the blade 4, and there are corresponding holes on the blade 4. The bolts position the blade 4.
[0013] A horizontal guide cylinder 203 is fixed inside the handle 2. One end of the guide cylinder 203 is fixed to the end of the handle 2, and one end of the pull rod 6 is slidably engaged with the guide cylinder 203 to improve the stability of the pull rod 6 sliding.
[0014] like Figure 5 As shown, two positioning holes 201 are connected to the side wall of the blade housing 1 via guide holes 202. The width of the positioning holes 201 is greater than the width of the guide holes 202, as shown. Figure 4 , Figure 7 As shown, the push button 3 includes a pressure block 303 that mates with the positioning hole 201. The upper end of the pressure block 303 is provided with an upper baffle 301, and the lower end of the pressure block 303 is provided with a lower baffle 304. The upper baffle 301 is located outside the handle 2, and the lower baffle 304 is located inside the handle 2. Figure 8As shown, the bottom of the lower baffle 304 is connected to a guide sleeve 305 that cooperates with the support column 601. A spring 602 is connected between the support column 601 and the guide sleeve 305. The side wall of the pressure block 303 is provided with a sliding groove 302. The pressure block 303 can be moved from one positioning hole 201 to another positioning hole 201 through the sliding groove 302.
[0015] When the pressure block 303 is in the positioning hole 201, under the action of the spring 602, the lower baffle 304 is pressed tightly against the inner wall of the handle 2. At this time, the height of the slide groove 302 is higher than that of the handle 2, so the push button 3 cannot slide. Press the push button 3 down so that the upper baffle 301 is pressed tightly against the outer wall of the handle 2. At this time, slide the push button 3, and the side wall of the guide hole 202 is inserted into the slide groove 302. The push button 3 can move from one positioning hole 201 to another positioning hole 201. When it moves to the positioning hole 201, under the action of the spring 602, the pressure block 303 is lifted up to achieve positioning. The positioning hole 201 at the front end indicates that the blade 4 is extended, and the positioning hole 201 at the rear end indicates that the blade 4 is retracted. The blade 4 can be pushed out and retracted by sliding the position of the push button 3 as needed. Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
