The invention discloses a lifting working table. The lifting working table comprises an upper platform and a lower platform, wherein at least one group of lifting arms is arranged between the upper platform and the lower platform, the upper end of the at least one group of lifting arms comprises a sliding part in linkage with the lifting arms, in the process that the upper platform displaces relative to the lower platform, the sliding part moves in the horizontal direction, the bottom of the upper platform is rotatably connected with a locking plate, and the length direction of the locking plate is consistent with the sliding direction of the sliding part; the locking plate is sequentially provided with a plurality of lock fasteners in clamping connection with the sliding part along the direction length; the lifting working table further comprises a handle, the handle is connected with the locking plate for controlling the locking plate to rotate, so that the locking plate is in the locked state or the unlocked state, and the adjustment and locking on the height of the upper platform are realized. The lifting working table is low in manufacturing cost, after complete folding, an elastic movable gap does not exist between the upper platform and the lower platform, and the close locking between the upper platform and the lower platform can be maintained.

The invention discloses a novel anti-theft bolt. The novel anti-theft bolt comprises a base. A main stud is clamped in the base, and one end of the main stud extends out of the base. Hinge pins are connected to the two sides of the main stud in the base in a clamped mode correspondingly. One end of each hinge pin penetrates through the base and extends out of the base. A fixing plate is fixedly connected to the top of the base. The fixing plate penetrates through the top of a reinforcing plate and extends out of the reinforcing plate. A spacer is arranged at the joint of the fixing plate and the reinforcing plate. Clamping beads are fixedly connected to the top of the reinforcing plate. According to the novel anti-theft bolt, the hinge pins, the fixing plate, the reinforcing plate, the spacer, the clamping beads, connecting rods and the like are arranged, the hinge pins and the main stud are connected in the clamped mode, and the fixing plate is matched with the reinforcing plate, so that the bottom of the main stud is fixed; the clamping beads and the connecting rods are matched to form inverted buckle shapes, so that the main stud is prevented from being pulled out, and a primary fastening effect and an anti-theft effect are achieved; and through the arrangement of a clamping plate, fixing columns, first screws, second screws, oblique plates, a fixing base and the like, a dual anti-theft effect is achieved.

The invention discloses a welding die locking device, and belongs to the field of die clamping. The welding die locking device comprises a supporting plate mounted on a machine tool slippage frame, and a locking cylinder and a tapered end fixing plate which are fixedly arranged on the supporting plate, wherein the tapered end fixing plate is fixedly connected with a piston rod of the locking cylinder through connection plates; a front tapered end and a rear tapered end module which are arrayed side by side in tandem are arranged at the bottom of the tapered end fixing plate; the rear tapered end module comprises a tapered end clamping block, a sliding tapered end, a spring and a fixed plate; a through sliding slot is formed in the tapered end clamping block; the sliding tapered end is arranged in the sliding slot in a sliding manner; the fixed plate is fixedly arranged at one end of the sliding slot; the spring is arranged between the sliding tapered end and the fixed plate. The spring is matched with the sliding tapered end, so that the welding die locking device can freely expand and retract front and back according to an actual distance so as to guarantee that the front tapered end is fully clamped and to improve the flexibility and the generality of equipment, and the application range is wide; and furthermore, the welding die locking device has the characteristics of being capable of adjusting the tightness of the spring, convenient to mount, simple in structure, low in purchase cost and the like.

The present invention provides a sealing unit for a feeder. The sealing unit can be assembled and disassembled with a relatively small force, the mounting direction is not limited, and a plurality of lips can be easily formed. The feeding device includes a feeding container that is opened at one side and a lid that covers the opening, wherein the feeding device is configured such that either one of an end of the feeding container and an end of the lid is disposed inside the other, a sealing member provided between an end portion of the feeding container and an end portion of the lid body is used for sealing, the sealing member is formed by a ring-shaped belt body, one end of which is bent and formed so as to provide a first concave portion for embedding at any one edge of the first concave portion, a lip portion contacting the other end portion on a surface opposite to a surface on the first concave portion is formed, and a second recess for embedding the other end of the sealing member is formed at an end for embedding the first recess.

The invention relates to a nuisanceless preservative for pears. The nuisanceless preservative comprises the following components in parts by weight: 0.3-0.5 part of calcium chloride, 2-3 parts of citric acid and 2-2.5 parts of starch. Furthermore, the invention also discloses a nuisanceless preservation method for the pears. The method comprises the following steps of (1) preparing a lotion according to the weight part of the components shown by claim 1; (2) mixing the lotion prepared in the step (1) and water according to the proportion of 1:((50-80), stirring uniformly, then putting the washed pears into the lotion for rinsing; and (3) coating propolis on the rinsed pears uniformly, then packaging with a refreshment paper bag. The preservative has low cost, is simple to prepare, is nuisanceless, can fully maintain vitamin and moisture, and has long preservation time.
