When drilling in a workshop, the canvas 5 is conveniently fixed on the mounting frame 4 through the mounting frame 4 and the connecting piece 6, the mounting frame 4 can be conveniently mounted on the down-the-hole hammer 1 through the matching of the fixing rod 2, the fixing plate 3 and the mounting piece 41, the friction force applied when the mounting piece 41 rotates can be reduced after the side, far away from the mounting frame 4, of the canvas 5 droops, the mounting piece 41 is positioned on the fixing rod 2 and can rotate, the mounting piece 41 is positioned on the fixing plate 3 and is opposite to the top of the down-the-hole hammer 1, so that a worker can conveniently rotate the whole canvas 5 through the lower side of the canvas 5, the equipment in the workshop can be isolated in a targeted manner, the splashed rock debris and the pollution of the mud to the original equipment in the workshop can be effectively reduced, simple structure and convenient installation.

Preferably, the mounting member 41 is provided as a bearing, and the bearing is sleeved on the fixing rod 2 to further facilitate the worker to rotate the whole canvas 5 on the ground.

With reference to fig. 3 and 4, in practical use, when the canvas 5 is fixed on the first connecting rods 43 by the bolts and the nuts, the nuts need to be screwed by using tools such as a wrench and a pliers, when the canvas 5 needs to be detached from the first connecting rods 43 for separate storage after drilling is completed, the nuts need to be unscrewed from the bolts by using tools such as a wrench, so that the detachment process of the canvas 5 on the first connecting rods 43 is complicated and inconvenient, eight second connecting rods 44 are provided for this purpose, and the connecting member 6 is improved as follows.

The eight second connecting rods 44 are fixedly connected end to end in sequence, vertical through holes are formed in the second connecting rods 44, the connecting piece 6 comprises eight fixing pins 61 and eight locking pieces 62 which are respectively arranged, the eight fixing pins 61 are respectively and vertically fixed on the upper portion of the first connecting rod 43, slots are formed in the upper ends of the fixing pins 61 close to the upper ends, the fixing pins 61 can be simultaneously inserted into the through holes of the eight second connecting rods 44, the locking pieces 62 comprise supporting seats 621, baffle plates 622, inserting rods 623 and springs 624, the two supporting seats 621 are arranged and fixed on the second connecting rods 44 at intervals, the baffle plates 622 are arranged between the two supporting seats 621, the inserting rods 623 are horizontally arranged and sequentially penetrate through the two supporting seats 621 and the baffle plates 622 and are fixedly connected with the baffle plates 622, the springs 624 are sleeved, the two ends of the inserting rod are respectively abutted against the support 621 and the baffle 622, and one end of the inserting rod 623 close to the baffle 622 is positioned above the through hole and can be inserted into the slot of the fixing pin 61.

During the use, wear to establish fixed pin 61 on canvas 5 and pass the through-hole of second connecting rod 44, after the through-hole that passes of fixed pin 61, insert the one end of inserted bar 623 in the slot, the spring 624 of compression state can promote baffle 622 all the time, make baffle 622 drive inserted bar 623 insert in the slot, when needs are dismantled canvas 5 from head rod 43, the one end of baffle 622 is kept away from to pulling inserted bar 623, make inserted bar 623 break away from fixed pin 61, just can realize the quick dismantlement to canvas 5, fixed pin 61 and retaining member 62 simple structure, and convenient for operation, under the prerequisite that need not use any instrument, can be quick from mounting bracket 4 with canvas 5, conveniently carry out the dismouting.

Referring to fig. 4, it is most advanced to process the upper end of fixed pin 61 and polish and form, and the pointed end can be convenient for pierce through canvas 5, need not punch in advance on canvas 5 under the prerequisite, and the fixed pin 61 of being convenient for wears to establish on canvas 5, punches on canvas 5 for in advance, and the precision that reduces to take place to punch is low to lead to the fixed pin 61 can not correspond with the hole on canvas 5 the condition.

Preferably, an inclined plane is formed at one end, close to the baffle 622, of the inserting rod 623, the end, provided with the inserting rod 623, of the inclined plane is inclined and downwards formed towards the support 621, and then after the fixing pin 61 is inserted into the through hole of the second connecting rod 44, the tip of the fixing pin 61 abuts against the inclined plane of the inserting rod 623, and then the inserting rod 623 can automatically perform secondary compression on the spring 624, and after the inserting rod 623 corresponds to the slot, the spring 624 subjected to secondary compression can push the baffle 622 to enable the inserting rod 623 to be inserted into the slot, so that the structure is simple, the installation of the canvas 5 can be completed on the premise that an operator does not need to pull the inserting rod 623, and the use of the operator is facilitated.

Referring to fig. 4, during the in-service use, when the staff takes canvas 5 off from mounting bracket 4, need many staff to stimulate many inserted bars 623 simultaneously and operate, just can take out all inserted bars 623 simultaneously from whole fixed pin 61, in order to be further convenient for the staff to dismantle canvas 5, shared more manpower when reducing the dismantlement canvas 5, so retaining member 62 still is provided with bead 625 to carry out following improvement to support 621 and inserted bar 623.

The inserted bar 623 is of a round bar-shaped structure, a gap is formed in the support 621 far away from the baffle 622, the rib 625 is fixed on the inserted bar 623, the length direction of the rib 625 is parallel to the axial direction of the inserted bar 623, the rib 625 is located in the gap, and one end, close to the baffle 622, of the rib 625 can abut against the support 621 far away from the baffle 622.

During the use, pulling inserted bar 623 is kept away from fixed little one end for the one end that bead 625 is close to baffle 622 breaks away from the breach completely, then at rotation inserted bar 623, loosen the inserted bar 623 after, under the secondary compression effect of spring 624, can make bead 625 butt on support 621, and then make the tip of inserted bar 623 can not insert back the slot once more in, after an staff takes out inserted bar 623 in proper order, just can take down canvas 5 from mounting bracket 4 smoothly, shared too much when can effectively reducing the dismantlement canvas 5, unnecessary manpower.

Refer to fig. 3, during the in-service use, fixed mounting has a plurality of helosis 7 on canvas 5 keeps away from one side of mounting bracket 4, it has rope 8 to system respectively in a plurality of helosis 7, can be with canvas 5's downside fixed connection in the workshop through rope 8, and then enable canvas 5 to strut better, increase canvas 5's isolation area effectively, helosis 7 can be so that behind the trompil on canvas 5, under the great action of gravity of canvas 5 self, it is difficult to appear the condition of tearing canvas 5 and damaging to pull through rope 8.

The embodiment of this embodiment is the utility model discloses preferred embodiment is not according to this restriction the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
