The invention discloses a conveniently-detached switch. The conveniently-detached switch comprises a base, wherein a switch shell is arranged above the base; a fixing rod is arranged at the top of the inner cavity of the switch shell; the bottom of the fixing rod is fixedly connected with the surface of a sliding rod; the sliding rod is positioned inside the inner cavity of the switch shell; a first sliding sleeve and a second sliding sleeve sequentially sleeve each of the two ends of the sliding rod from the inside to the outside; the two first sliding sleeves are communicated with the two second sliding sleeves; one ends, away from the first sliding sleeves, of the second sliding sleeves run through the switch shell, stretch out of the switch shell and are fixedly connected with one ends of protruding blocks. Through improvement on the switch shell and through cooperative use of the sliding rod and the protruding blocks, the first sliding sleeves and the second sliding sleeves slide on the sliding rod to effectively detach the switch shell, so that an effect of convenient detachment is achieved; through cooperative use of pull rods and clamping blocks, a resetting spring resets the pull rods to effectively achieve a resetting effect, so that detachment of the switch shell is facilitated and the effect of convenient detachment is achieved.

The invention discloses a vibration device for picking barbary wolfberry fruits. The vibration device comprises a body, a first connecting plate is fixedly connected onto the inner surface of the bodyand connected with two rotating rods in a penetrating manner, a plurality of semicircular rings are arranged on the outer surfaces of the two rotating rods in a sleeving manner, first fixed grooves are fixedly formed in the two corresponding ends of the two semicircle rings, a bolt is embedded into a space between every two first fixed grooves in a penetrating manner, a nut is embedded into the far end of each bolt, a plurality of second connecting rods are fixedly connected on the outer surfaces of the two semicircular rings, a circular plate is fixedly connected at one end, close to the first connecting plate, of the outer surface of each rotating rod, second connecting plates are fixedly connected at the tops of the two rotating rods, and two first motors are fixedly connected at the bottoms of the second connecting plates. According to the vibration device, the two rotating rods are rotatably connected with the first connecting plate and the second connecting plates, bearings arearranged at joints, and friction among the rotating rods, the first connecting plate and the second connecting plates is reduced.

The invention relates to the field of foundation survey, in particular to a survey device for foundation construction. A survey device for foundation construction includes a survey needle, a detection disc, a transmission mechanism and a clamping assembly. The detection plate includes an upper plate and a lower plate arranged below the upper plate. Vertical through holes are arranged at the axial positions of the upper plate and the lower plate, and the survey needle is arranged vertically and passes through the vertical through holes of the upper plate and the lower plate in sequence downward. The clamping assembly is arranged on the lower plate. The transmission mechanism is configured to drive the clamping assembly to work under the pressing of the upper plate and the lower plate when the upper plate moves downward relative to the lower plate, so that the clamping assembly clamps the survey needle, thereby preventing the detection needle from moving up and down. When the surveying device for foundation construction of the present invention needs to measure specific values, the surveying device is pulled out of the ground, and the transmission device acts on the clamping component, so that the clamping component shrinks and clamps the surveying needle, so as to achieve the effect of fixing the surveying needle It is convenient for further measurement of specific values.

The invention discloses an oven heating device. The oven heating device comprises a box body, wherein a fixed block is fixedly connected to the left side of an inner cavity of the box body, a chute isformed in the fixed block, a sliding block is slidably connected in the chute, a spring is fixedly connected to the top of an inner cavity of the chute, and the end, away from the top of the inner cavity of the chute, of the spring is fixedly connected with the sliding block; the right side of the sliding block is fixedly connected with a moving rod. According to the oven heating device, the effect of enabling the sliding block to move inside is achieved through the arrangement of the chute, and the effect of driving the sliding block to reset is achieved through the arrangement of the spring; after an electromagnetic ring is arranged, the electromagnetic ring is in contact with an armature, and correspondingly the effect of driving the moving rod to move is achieved. Through the arrangement of a first contact switch and a second contact switch, the effect of heating a heating plate through heating pipes is achieved, and meanwhile, the problems that since the bottom of the heating plate cannot be heated, baked food is not uniformly heated and the taste of the food is influenced are solved.
